I'm looking for some guidance on edge conditions for a composite steel deck (1.5" deck + 4-5" concrete w/ slope). I am working on a rehab job designing a floor for a 2nd story covered walkway to replace the existing (corrosion and poor design all around). I know its not the ideal choice but its in a dry climate, no snow/salts.
The deck has a simple span ~4.5 feet so really not far. The building jogs out and runs parallel to the span (see highlighted area in photo below) at each end of the deck. There is not currently support under the existing deck in this area.
My question is, should there be support under this edge? I plan to show a pour stop attached to the deck. Fairly standard slab reinforcing (also shown below, detail is reversed) will be included at this edge. I can't seem to find any good references explaining how to handle an "unsupported edge" parallel to the deck ribs. Conceptually, it seems like this should span just fine there. But I need a gut check before I finalize it. I always deal with projects will support on all 4 sides so this made me second guess things.
Any thoughts/recommendations are appreciated!
